“In fact it seemed when the housing rush was going on rents were rising during a self perpetual buying frenzy for houses to get out of rentals.”
Comment: I can’t help thinking it was a frenzy of illegal immigrants barging themselves, or squeezing themselves, ahead of their time, into all of our cities. I doubt it was Americans having babies causing the population boom. Most Americans have none or two kids. I heard Mexicans like to have a lot of kids.
